Description

Automatic assembling equipment for blade lock

Technical Field

The invention relates to the field of lockset processing, in particular to automatic assembling equipment for a blade lock.

Background

The padlock is used as a traditional lockset, and a lock body of the padlock is provided with a buckled annular or straight-line-shaped metal stem, namely a 'lock beam', so that the padlock is directly buckled with the lock body through the lock beam to form a closed lockset. The current blade padlock, as shown in fig. 1-2, includes a lock body 101 and a shackle 102. The processing steps of such blade padlocks are generally: the blank is perforated, the pins and the choke plug are installed, polishing is carried out, the lock beam 102, the steel balls 204 and the lock cylinder 203 are installed, and then the choke plug is pressed to seal the lock cylinder in the lock cylinder hole. The blank is provided with a lock beam hole 103, a lock cylinder hole 104, a pin hole 105 and a steel ball assembling hole 106 which is communicated with the lock beam hole and the lock cylinder hole and used for loading steel balls. As shown in the figure, the steel ball assembly hole is completely arranged in the lock body, so that a hole needs to be punched from the side wall of the lock body when the hole is opened, and a fabrication hole 107 is left on the side wall of the lock body; the fabrication hole needs to be closed by a bulkhead 201. The applicant filed three prior patent applications for the purpose of implementing a mechanized and automated loading of the bulkhead 201 into the fabrication bore 107 and the pin 202 into the pin bore 105, thereby forming a complete lock body.

In order to realize automatic assembly of the lock body of the existing blade padlock, the applicant submits a Chinese patent application with the application number of '201911347250.1' in the end of 2019, and the application provides a blade assembly device which comprises a blade sleeve feeding mechanism, a blade assembly mechanism and a feeding clamping mechanism; the blade assembly mechanism comprises a moving pair capable of moving along the axial direction and the radial direction of the blade sleeve, and a blade cartridge clip assembly and a blade assembly which are arranged on the moving pair; the blade cartridge clip assembly comprises a base, a plurality of blade rails matched with the blades in shape are arranged on the base, and a blade pressing assembly is arranged in each blade rail; the blade pressing assembly comprises a blade pressing block which is arranged on the blade rail in a sliding mode and a blade pressing spring which drives the blade pressing block to press the blade; the tail end of the blade track is provided with a front end cover plate for abutting against the blade, and the output end of the blade assembly is positioned above the tail end of the blade track. The blade assembling mechanism has the advantages of simplifying the blade assembling mode and improving the blade assembling efficiency.

On the basis, the applicant improves the blade assembly mechanism in the year 2020, and provides a Chinese utility model patent with the application number of 202022839829.4, and the scheme provides a blade assembly mechanism which comprises a material receiving seat, a blade frame and a plurality of groups of blade press-fitting assemblies; the blade frame is arranged on the material receiving seat, a plurality of material rods used for connecting blades of different types in series are detachably and longitudinally erected on the blade frame, and a plurality of material receiving grooves corresponding to the material rods are formed in the material receiving seat; every connects the silo all to correspond and is provided with a set of blade pressure equipment subassembly, and the output orientation of blade pressure equipment subassembly connects the silo bottom to can release the blade level that connects the silo lowermost end. This blade assembly mechanism realizes vertical feeding and the horizontal installation of blade to need not to use the fixed blade row group of viscose, whole scheme structure is simpler, and it is more convenient to operate.

However, the two sets of blade padlock assembling machines can only realize identification based on the key teeth, and the blades are correspondingly arranged in the blade sleeves; during actual use, the lock cylinder still needs to be installed into the lock body manually, and the specific reason is that on one hand, the blade sleeve needs to be provided with the roller pin to match with the blade, and then the lock cylinder can be installed into the lock cylinder hole of the lock body. The structure that the blade cover cooperates with the bearing pin installation can refer to the blade lock core that china utility model patent document with publication number "CN 204609488U" describes. On the other hand, the assembly precision of the lock core and the lock core hole is higher. As shown in fig. 1 and 2, the blank cap is used for installing at the opening of the cylinder hole 104, so the opening of the cylinder hole 104 is slightly larger, so a step surface 108 is formed in the opening of the cylinder hole 104, and during the process of installing the cylinder 203 into the cylinder hole 104, the cylinder 203 is easily interfered by the step surface 108 due to a small error in size, which may cause equipment shutdown and affect installation efficiency.

Therefore, the two blade padlock assembling machines can only realize semi-automatic processing, and after the blades are arranged in the blade sleeves, the rolling needles need to be manually installed and arranged in the lock cylinder holes, so that the assembling efficiency of the blade locks is greatly limited.

In addition, the steel ball 204 is loaded into the steel ball assembly hole 106, and the steel ball 204 needs to be lubricated by grease, then is placed into the lock cylinder hole and pressed into the steel ball assembly hole 106. In the past, steel ball assembly does not have a convenient mechanical structure, and manual finger pressing is adopted, so that the workload is large, the working efficiency is low, and a large amount of repeated work easily damages hands of workers. On the basis, the Chinese patent publication with the prior patent publication number of CN110924750A of the applicant of the present application describes a steel ball assembling device and an assembling method of a blade padlock, and the steel ball assembling device comprises a lock body clamp used for clamping and fixing a lock body; the lock beam assembly component is used for pressing the lock beam arm of the lock beam into the lock beam hole of the lock body; the steel ball feeding pair is used for loading two steel balls which are infiltrated and lubricated into a lock cylinder hole of the lock body; and the air pressure assembly is used for plugging the lock cylinder hole of the lock body and respectively pressing the two steel balls into the steel ball assembly holes of the lock body through air flow. This steel ball assembly quality adopts the scheme of high-pressure gas pressure equipment, replaces traditional manual assembly's scheme, promotes work efficiency greatly, reduces the hand work volume. In the scheme, two steel balls soaked with grease are required to be loaded into a lock cylinder hole of the lock body, but a structure for realizing steel ball lubrication and loading is not provided. In addition, the scheme is difficult to ensure that the steel balls are always loaded into the steel ball assembly holes, and the possibility of subsequent processing of the steel balls without being loaded exists, so that the subsequent processing efficiency is influenced, and accessories or equipment are easily damaged.

Finally, as mentioned above, the prior patent proposals of the above-mentioned application numbers "201911347250.1" and "202022839829.4" do not realize the fully automatic installation of the blade padlock, and after the steel ball assembly and the blade assembly are completed, the lock cylinder (the blade sleeve and the blades and needle rollers thereon) needs to be manually installed inside the lock body, and then the lock cylinder is placed in the blank cap assembly mechanism for blank cap installation. Because the lock body needs to be manually installed in the lock body supporting clamp of the blank cap assembling mechanism, manual alignment adjustment can be carried out. Therefore, the lock core assembly and the blank cap installation are not affected by the hole opening error of the lock core hole on the lock body. But the scheme is semi-automatic installation, and the processing efficiency needs to be improved; however, if the semi-automatic installation described in the above-mentioned prior patent is to be improved to the fully automatic installation, it is necessary to consider the influence of the error of the opening of the cylinder hole, and specifically, when the cylinder hole 104 is formed in the lock body, there is a certain allowable machining range, which causes a certain error in the distance between the cylinder hole 104 and the lock body side wall. If the opening error of the lock cylinder hole 104 is not considered, it is difficult to ensure that interference occurs due to small deviation of hole positions when the lock cylinder is automatically installed and the blank cap is automatically installed, and smooth installation cannot be realized.

In the scheme, the lock body clamping device 3 receives the lock body from the tail end of the lock body feeding device 2, and conveys the lock body to the steel ball mounting device 4, the lock cylinder assembling device and the blank cap assembling device 5 to mount the steel ball, the lock cylinder and the blank cap respectively. As shown in the figure, the lock body clamping device 3 includes a lock body conveying mechanism, and a lock body clamp disposed on the lock body conveying mechanism. The lock body conveying mechanism comprises a station moving pair, a fine adjustment moving plate 32 movably arranged on the station moving pair, and a locking cylinder 33 used for locking the fine adjustment moving plate 32 relative to the station moving pair. The lock body clamp is disposed on the fine adjustment moving plate 32.

In addition, a positioning rod 41 is provided on the frame 1, and the positioning rod 41 and the lock body clamping device 3 are combined to construct a lock body station fine adjustment structure. The positioning rod 41 can be independently arranged on the frame 1 and is only used for fine adjustment of the station of the lock body; or may be built into the steel ball mounting device 4 in the present embodiment as shown below. The lock body clamp in the lock body clamping device 3 in the scheme is used for clamping and fixing the lock body, and the lock body conveying mechanism is used for conveying the lock body among all stations. Different from the prior art, the lock body conveying mechanism in the scheme further comprises a fine adjustment moving plate 32 which is arranged on the station moving pair in a sliding mode besides the station moving pair, and the lock body clamp is installed on the fine adjustment moving plate 32. In the above structure, when the positioning rod 41 extends into the lock cylinder hole, the fine adjustment moving plate 32, the lock body clamp thereon, and the lock body slide and fine adjust relative to the station moving pair due to the hole position of the lock cylinder hole, so as to ensure the positioning rod 41 to align with the center of the lock cylinder hole. After fine adjustment, the fine adjustment moving plate 32 is locked relative to the station moving pair based on the locking air cylinder 33, so that the lock body clamp is ensured to be fixed relative to the station moving pair, then the station moving pair can move to a corresponding station based on a program set by equipment to install the lock cylinder and the blank cap, and station alignment is ensured when the lock cylinder and the blank cap are installed.

In the scheme, the station moving pair comprises a station moving plate 311 movably arranged on a slide rail of the rack 1 and a driving motor 312 for driving the station moving plate 311 to move. The driving motor 312 drives the station moving plate 311 to move along the sliding rail through the screw rod assembly 313. The driving motor 312 adopts a servo motor, and the station moving plate 311 is controlled based on the screw rod assembly 313 so as to accurately control the movement of the lock body between the stations. A fine adjustment slide rail is arranged on the station moving plate 311, and the fine adjustment moving plate 32 is arranged on the fine adjustment slide rail in a sliding manner. Furthermore, a position limiting part 321 is arranged on the station moving pair and/or the fine adjustment moving plate 32, and the fine adjustment moving plate 32 moves relative to the station moving pair within the range limited by the position limiting part 321. The moving range of the fine adjustment moving plate 32 can be limited based on the limiting component 321, and the fine adjustment moving plate 32 can be pushed to move through the limiting component 321 when the station moving pair moves.

As shown in fig. 4, the output shaft of the locking cylinder 33 passes through the fine adjustment moving plate 32, and the output shaft of the locking cylinder 33 can press the station moving plate 311 to lock the fine adjustment moving plate 32 on the station moving plate 311. Of course, other structures for holding the fixed fine adjustment moving plate 32 may be employed by those skilled in the art. In addition, the lock body clamp includes a fixed block 341 and a lock body clamping cylinder 342 fixedly installed on the fine adjustment moving plate 32, and a movable block 343 connected to an output end of the lock body clamping cylinder 342. The lock body clamping cylinder 342 drives the movable block 343 to approach or separate from the fixed block 341.

The initial position of the lock body clamping device 3 is located at one side of the tail end of the lock body feeding device 2, the tail end of the lock body feeding device 2 corresponds to a clamping opening of the lock body clamp, the lock body can be pushed into the lock body clamp through pushing of the lock body feeding air cylinder, and feeding of the lock body is completed.

As shown in fig. 3, 10a to 10c, in the present embodiment, a steel ball feeding assembly 7 is further constructed on the frame 1, and the steel ball feeding assembly 7 shown in the figure is located above the initial position of the lock body clamping device 3, that is, after the lock body is pushed into the lock body clamp to complete the lock body feeding, the steel ball feeding process can be performed. In another preferred scheme, the steel ball feeding assembly 7 is arranged above the tail end of a lock body feeding slideway of the lock body feeding device 2, and a steel ball feeding process can be realized before the lock body waits for feeding and pushing to the lock body clamp. The steel ball feeding assembly 7 comprises a base 71 and a pressing assembly 79 arranged above the base 71. A feeding channel 72, an oil storage chamber 73 which is arranged inside the base 71 and communicated with the feeding channel 72, a discharge hole 74 which is arranged at the bottom of the base 71, and a movable receiving block 75 which is movably arranged between the lower end of the feeding channel 72 and the upper part of the discharge hole 74 are constructed inside the base 71. The upper end of the feeding channel 72 is used for being connected with the steel ball feeding rail 70, and the output end of the downward pressing component 79 faces the upper end of the feeding channel 72. The movable receiving block 75 is used for receiving a plurality of steel balls on the lower end opening of the feeding channel 72, transferring the steel balls to the discharging port 74 and releasing the steel balls. Specifically, the movable receiving block 75 is provided movably inside the base 71, and the movable receiving block 75 is connected to the output end of the translation driving cylinder 76. The movable receiving block 75 is provided with a receiving hole 751 for receiving a plurality of steel balls, and the lower end of the receiving hole 751 is closed by the base 71 below the receiving hole and is opened only when the movable receiving block moves to the discharge port 74. In the technical scheme, the steel balls in the bearing holes 751 are supported by the bottom of the base 71, and when the steel balls move to the discharge hole 74, the steel balls in the bearing holes 751 can fall from the discharge hole 74.

The steel ball feeding assembly 7 comprises a base 71 and a pressing assembly 79, the upper end of a feeding channel 72 in the base 71 is connected with a steel ball feeding rail 70, steel balls are pushed to move downwards along the feeding channel 72 based on the pressing assembly 79, the steel balls are infiltrated by grease due to the fact that an oil storage cavity 73 is communicated with the feeding channel 72 in the downward process, the lower end of the feeding channel 72 is connected with a movable connecting block 75, the steel balls are transferred to a discharge hole 74 to be released, and then the steel balls fall into a lock core hole of a lock body.

Considering that the steel balls stained with grease may adhere to the discharge port 74, they cannot fall from the discharge port 74 based on gravity. In this case, there is also provided a blowing duct 77 in the inside of the base 71 in the solution, the end of the blowing duct 77 being open towards the upper end of the discharge port 74. Thus, when the steel balls are discharged, air pressure blowing can be carried out based on the air blowing pore channel 77, and the steel balls and part of grease adhered to the steel balls are blown down into the lock cylinder hole. Thereby ensuring that the steel ball falls into the lock body.

As shown in the figure, a plurality of grease passages 731 are arranged between the oil storage chamber 73 and the feeding passage 72 on the edge, and an oil filling hole 732 communicated with the oil storage chamber 73 is also arranged on the side wall of the base 71. This scheme is based on many grease passageways 731 communicate with each other to guarantee that there is a longer section route to fill in the material loading passageway 72 with grease, thereby guarantee that the steel ball of inside transport is fully soaked. In a further scheme, the cross section of at least part of the feeding channel 72 above the oil storage cavity 73 is circular and is matched with the outer diameter of the steel ball. The section of the feeding channel 72 beside and below the oil storage cavity 73 is circular or rectangular larger than the outer diameter of the steel ball, or square tangent to the outer diameter of the steel ball. In this embodiment, at least a portion of the cross-section of the feeding channel 72 above the oil storage cavity 73 is circular and is adapted to the outer diameter of the steel ball, where the outer diameter of the steel ball is adapted to the feeding channel 72, and the outer wall of the steel ball passes through the inner wall of the feeding channel 72, so that the grease in the feeding channel 72 below is difficult to overflow from above the feeding channel 72. And the feeding channel 72 beside and below the oil storage chamber 73 has larger hole diameter than the steel ball or is tangent to the steel ball. Therefore, a larger gap exists between the outer wall of the steel ball and the inner wall of the feeding channel 72, so that the grease can conveniently permeate and flow, and the steel ball can easily fall.

The lock body on the lock body clamping device 3 firstly carries the steel ball on the steel ball feeding assembly 7 and then moves to the steel ball mounting device 4 to mount the steel ball. As shown in fig. 3 and 11a to 11c, the steel ball mounting device 4 includes a positioning rod 41 slidably disposed and having a lower end portion capable of extending into or retracting from the cylinder hole, and a sealing sleeve 42 fitted around the positioning rod 41. An air passage 43 is provided in the positioning rod 41, and the lower end of the air passage 43 extends to the lower end of the positioning rod 41. Specifically, a lower slide seat 44 is arranged on the rack 1, the upper end of the lower slide seat 44 is connected with the output end of a lower driving part 45, the upper end of a positioning rod 41 is connected on the lower slide seat 44, an air passage 43 extends to the lower slide seat 44, and an air inlet hole is formed on the side wall of the lower slide seat 44. The lower slide 44 and the upper positioning rod 41 are driven by the lower driving part 45 to move longitudinally along the machine frame 1. A positioning rod 41 in the steel ball mounting device 4 can stretch into or withdraw from a lock cylinder hole, an air passage 43 arranged in the positioning rod 41 is used for introducing high-pressure gas into the lock cylinder hole, and meanwhile, a sealing sleeve 42 on the outer side of the positioning rod 41 seals the lock cylinder hole, so that the high-pressure gas can only flow to a lock beam hole from the lock cylinder hole through a steel ball assembling hole, and the steel ball is pressed to the steel ball assembling hole to complete steel ball assembly.

On the basis, the descending driving component 45 in the scheme drives the lower end part of the positioning rod 41 to descend into the lock cylinder hole below the upper end surface of the steel ball assembling hole, so that whether the steel ball is assembled in the steel ball assembling hole can be judged by whether the positioning rod 41 is blocked in the descending process. When the steel ball is not blown into the steel ball assembly hole, the structure can give wrong feedback in time, and then can suspend equipment operation and inform workers to carry out trimming, and avoid accessories or equipment damage caused by subsequent processing. In a specific embodiment, the downward driving means 45 can drive at least two strokes of downward movement of the positioning rod 41. In the scheme, in the first section of stroke, the lower end part of the positioning rod 41 descends into the lock cylinder hole above the steel ball assembling hole, so that the air outlet of the air passage 43 at the lower end of the positioning rod 41 is close to the steel ball, and the steel ball is favorably loaded into the steel ball assembling hole. In the second stroke, the lower end of the positioning rod 41 moves downward into the lock cylinder hole below the upper end face of the steel ball assembling hole to judge whether the steel ball is installed in the steel ball assembling hole. The two-stage downward stroke of the downward driving part 45 for driving the positioning rod 41 can be realized by using one driving part or two driving parts.

As further shown in the figure, the lower end of the positioning rod 41 is in a frustum shape, and the air outlet of the air passage 43 is arranged on the inclined plane of the frustum shape. This technical scheme has two aspects's advantage: on one hand, the lower end part of the positioning rod 41 is in a frustum shape, and when the positioning rod 41 extends into the opening position of the lock cylinder hole, guiding alignment can be carried out, so that the positioning rod 41 can conveniently extend into the lock cylinder hole. On the other hand, the air outlet of the air passage 43 is arranged on the frustum-shaped inclined plane, high-pressure air is obliquely blown out from the air outlet of the air passage 43, the high-pressure air forms spiral air flow in the lock cylinder hole below the positioning rod 41, and the steel ball moves in the lock cylinder hole below the positioning rod 41, so that the steel ball is favorably loaded in the steel ball assembling hole. The intermediate section of the positioning rod 41 is configured as a tapered region 48 having a larger outer diameter at the upper end and a smaller outer diameter at the lower end, and the outer diameter of the positioning rod 41 below the tapered region 48 is smaller than or equal to the minimum inner diameter of the tapered region 48. As shown in fig. 11c, the tapered area 48 of the detent lever 41 can abut against the lock cylinder hole of the lock body, and the opening edge of the lock cylinder hole abuts against the tapered area 48, so that the outer diameter of the detent lever 41 below the tapered area 48 is necessarily smaller than the inner diameter of the lock cylinder hole, thereby facilitating the insertion of the detent lever 41 into the lock cylinder hole. In the second step of descending by the positioning rod 41, the tapered region 48 can abut against the cylinder hole of the lock body, and the cylinder hole is completely aligned with the positioning rod 41. In this case, the fine adjustment moving plate 32 is locked to the station moving plate 311 by the locking cylinder 33, thereby completing the station fine adjustment process and accurately ensuring that the cylinder hole is completely aligned with the positioning rod 41.

In addition, a sealing ring 46 is arranged on the lower end part of the sealing sleeve 42, and the sealing ring 46 is used for being attached to the lock body end face on the opening edge of the lock cylinder hole. In the solution described in the prior patent document with the publication number "CN 110924750A", the plug is used to extend into the cylinder bore to ensure tightness. But the proposal needs to ensure that the plug is attached to the inner wall of the lock cylinder hole so as to ensure the tightness. But it tends to make it difficult to install the plug into the cylinder bore. The sealing sleeve 42 of the scheme is provided with the sealing ring 46 at the lower end, the sealing ring 46 is a lock body end face which is attached to the edge of the opening of the lock cylinder hole in a sealing mode, so that the sealing sleeve 42 and the sealing ring 46 on the sealing sleeve can be sealed without extending into the lock cylinder hole, and the scheme is simpler. In a further preferable scheme, a sealing pressure spring 47 is further sleeved on the positioning rod 41, the upper end of the sealing pressure spring 47 is pressed against the positioning rod 41, and the lower end of the sealing pressure spring 47 is pressed against the sealing sleeve 42. In the scheme, a sealing pressure spring 47 is adopted to press the sealing sleeve 42 so as to ensure that the lower end of the sealing sleeve 42 is tightly sealed with the end face of the lock body on the opening edge of the lock cylinder hole.

And in the process of installing the steel balls, the device on the other side of the equipment synchronously operates. After the rotor plate 62 receives the blade cover from the end of the blade cover feeding assembly 61, the blade assembling mechanism 63 loads the blade into the blade cover based on the identification signal of the key bit. The improvement of the scheme is that as shown in figures 3 and 5, a blade sleeve conveying mechanism is arranged on the frame 1 on one side of the turntable 62 at the downstream of the blade assembling mechanism 63, and comprises a blade sleeve translation pair 81 and a blade sleeve lifting pair 82 arranged on the blade sleeve translation pair 81. The blade sleeve lifting pair 82 is provided with a blade sleeve clamp 83 for clamping the blade sleeve and the upper blade thereof, and a roller pin assembly 84 for installing the roller pin on the blade sleeve. The lock cylinder assembly device further comprises a blade sleeve press-mounting component 85, when the lock body clamping device 3 and the blade sleeve conveying mechanism move to the same station, the blade sleeve press-mounting component 85 is used for mounting the lock cylinder into the lock cylinder hole, in the scheme shown in the figure, the blade sleeve press-mounting component 85 is arranged on the blade sleeve lifting pair 82, and in the alternative scheme, the blade sleeve press-mounting component 85 can be arranged on the guide frame. In this embodiment, after the blade assembly is completed, the blade sleeve clamp 83 clamps the blade sleeve and the blade thereon, and the needle assembly 84 can install the needle into the needle groove of the blade sleeve (in this state, the blade sleeve clamp 83 is partially decompressed, as described below). And the lock core is taken down from the turntable 62 based on the blade sleeve lifting pair 82, then is transferred to a corresponding station based on the blade sleeve translation pair 81, and is installed into a lock core hole of the lock body through the blade sleeve press-fitting assembly 85, so that the automatic installation of the lock core is completed. Based on the structure, automatic assembly of the lock cylinder can be realized, and the prior patent documents with the application numbers of 201911347250.1 and 202022839829.4 are combined. The full-automatic assembly of the blade lock can be realized, and therefore the assembly efficiency of the blade lock is improved.

In the embodiment shown in fig. 6 and 7, the blade cover jig 83 includes two oppositely disposed clamping blocks 831, and at least one of the clamping blocks 831 is capable of moving toward or away from the other clamping block 831. A blade sleeve clamping opening 832 for clamping the blade sleeve and the upper blade thereof, a needle roller positioning opening 833 for receiving the needle roller from the tail end of the needle roller feeding mechanism, and a needle roller press-fitting passage 834 for communicating the needle roller positioning opening 833 with the blade sleeve clamping opening 832 are formed between the clamping surfaces of the two clamping blocks 831. The output end of the needle assembly 84 is capable of loading the needles in the needle alignment openings 833 from the needle press-fitting passages 834 into the vane pocket of the vane pocket alignment openings. In the process that the roller pins pass through the roller pin press-fitting channel 834, the two clamping blocks 831 elastically and flexibly press the roller pins. In this embodiment, a needle mounting assembly 84 is provided, and a needle positioning hole 833 for receiving a needle and a needle press-fitting passage 834 for communicating the needle positioning hole 833 with the vane pocket clamping hole 832 are formed in the vane pocket clamp 83. In a further scheme, the caliber of the needle roller press-fitting channel 834 is from large to small from the needle roller positioning hole 833 to the blade sleeve positioning hole. In the scheme, the caliber of the roller pin press-fitting channel 834 close to the roller pin positioning hole 833 is larger, and the caliber of the roller pin press-fitting channel close to the blade sleeve positioning hole is smaller. With this construction, it is easier to press the needle rollers into the needle roller press-fitting passage 834 and to guide the vane hub positioning holes step by step.

After the vane sleeve and the upper vane thereof are clamped and positioned in this way, the ball feeding assembly 800 can add the needle roller into the needle roller positioning hole 833, and press-fit the needle roller into the needle roller groove in the side wall of the vane sleeve through the output end of the needle roller assembling assembly 84. In the press fitting process, the two clamping blocks 831 elastically and flexibly compress the needle rollers to prevent the needle rollers from inclining or falling. Based on this, can realize that the kingpin is automatic to be assembled to the blade cover to provide the basis for the full automatic assembly of lock core. In the illustrated embodiment, the clamping block 831 is connected to a clamping cylinder 835, and the needles are pressed through the needle pressing channels 834. In the technical scheme, the clamping blocks 831 are controlled by cylinders, the cylinders are controlled by air channels and air valves on the air channels, and the clamping blocks 831 can be clamped tightly and not loosened in a pressure maintaining state. In a partially depressurized state, such as when the air pressure drops from 4KG to 2KG, the needles are allowed to press tightly through the needle-pressing channels 834.

Further, the needle assembly 84 includes a needle assembly cylinder 841, and a needle push plate 842 connected to an output end of the needle assembly cylinder 841. The needle roller pushing piece 842 is a piece body matched with the needle roller press-fitting channel 834. In this embodiment, the needle roller pushing piece 842 is a piece body matched with the needle roller press-fitting channel 834, which means that the thickness of the needle roller pushing piece 842 is matched with the caliber of the needle roller press-fitting channel 834, and the length is matched with the depth of the needle roller press-fitting channel 834.

As shown in fig. 3, 8 and 9, the frame 1 is further provided with a guide frame 9 for guiding the lock cylinder into the lock cylinder hole, and a guide sleeve 90 is longitudinally movably arranged on the guide frame 9. The specific scheme is that a longitudinal slide rail 91, a sliding frame 92 slidably disposed on the longitudinal slide rail 91, a guide sleeve 90 mounted on the sliding frame 92, and a sliding cylinder 93 having an output end connected to the sliding frame 92 are disposed on the guide frame 9. The sliding cylinder 93 drives the sliding frame 92 and the guide sleeve 90 thereon to move along the longitudinal sliding rail 91. When the lock body clamping device 3 is transferred to the lower part of the guide frame 9, the guide sleeve 90 longitudinally moves downwards and is positioned on the lock cylinder hole of the lock body, the blade sleeve transfer mechanism is transferred to the upper part of the guide frame 9, and the blade sleeve press-fitting assembly 85 is used for mounting the lock cylinder into the lock cylinder hole. Further, the outer wall of the lower end part of the guide sleeve 90 is in a taper sleeve shape with a small outer diameter at the lower end and a large outer diameter at the upper end, and the lower end part of the guide sleeve 90 can extend into the lock cylinder hole of the lock body. The inner hole of the guide sleeve 90 is a taper hole with a large caliber at the upper end and a small caliber at the lower end, and the diameter of the lower end of the inner hole of the guide sleeve 90 is smaller than or equal to the minimum inner diameter of the lock cylinder hole.

In the above scheme, the blade sleeve clamp 83 is used for clamping the lock cylinder, the blade sleeve press-fitting component 85 is used for installing the lock cylinder into the lock cylinder hole, and the guide sleeve 90 on the guide frame 9 is adopted in the scheme to guide the lock cylinder press-fitting process, specifically, the lower end part of the guide sleeve 90 can extend into the lock cylinder hole of the lock body, and the inner hole is in a taper hole shape. When the lower end of the guide sleeve 90 is fitted into the lock cylinder hole, the blade sleeve press-fitting assembly 85 can be very conveniently aligned with the inner hole of the guide sleeve 90 (because the upper end of the guide sleeve has a larger caliber) in the lock cylinder press-fitting process, and the lock cylinder hole is gradually aligned with the tapered inner hole in the press-fitting process. Because the aperture of the lower end part of the inner hole of the guide sleeve 90 is smaller than or equal to the minimum inner diameter of the lock cylinder hole, the lock cylinder is not interfered by a step surface in the process of assembling the lock cylinder, and the lock cylinder can be quickly and stably installed. In addition, the outer wall of the lower end of the guide sleeve 90 is also constructed into a taper sleeve shape, which is beneficial to the guide sleeve 90 to be quickly aligned and installed in the lock cylinder hole of the lock body in the descending process.
